This subclass covers only single or combined, e.g. multistage, operations not fully classifiable in a single other subclass

In this subclass the following terms or expressions are added with the meanings indicated :

- "disposal" means the discarding, e.g. dumping, or
destroying of waste or its transformation into something
useful or harmless;
- "solid waste" includes waste which, although it has liquid
content, is for practical purposes handled as solid
